Hi guys, I'm having a serious issue with exporting 1080x1920 videos on my M1 Mac Mini.
Premiere Pro is fully up to date (as of 15.09.2021). the videos are fairly long in length - between 40 and 50 minutes, and each have nested sequences of .mp4 alpha layers, a few alpha layers for graphic countdown timers and some PNG files.
In terms of effects, very small layer masks with motion tracking (top right of screen to hide a title that slides in and out behind a timer) and some slight colour correction for exposure but nothing heavy.
There are two main video layers (camera 1 & 2), and 7 tracks for .mp4 alpha animations and nested sequences. (see screenshots)
I have had some success with exporting the alpha tracks seperately as 1 big animation file, and then baking the two together, but it still sometimes causes glitches after export (and adds 40 minutes per video to export), while I have 6 hours of content to deliver per week.
I have seen slightly less glitching by using Premiere to export natively as opposed to using Media Encoder, but this obviously eats up workflow.
To be clear - there are absolutely no glitches in-program, and playback is perfect. Rendering is not an issue either. The glitches only appear post-export on the final files. Mostrly they are 1 or 2 frames of an entire yellow screen, similar to the 'Media Pending' screen. Sometimes certain elements of the video glitch by themselves.
Footage was shot on Canon 5D Mk. IV's - 1080x1920 @2926_2.97fps, and the sequences are all set up as the same - 1080x1920, 29.97fps. Its definitely not a footage issue, as I can export the footage without error.
Export settings are H.264, Custom (Max Render Quality, Max depth), VBR 1 Pass. I am currently trialling using software encoding only, as I have tried just about everything under the sun using Hardware Encoding but not found a fix yet.
Any help will be greatly appreciated!
Many thanks,
Mike Savage.
